FLANGED PIPE 0R nosn CONNECTION.

Application filed my 19, 1922. sehaliid. ante;

T0 aZZ whom it mag concern:

Be it known that I, MARTIN J. HEKKING, a citizen of the United States of America, and a resident of Brooklyn, county of" Kings, and State of New York, have invented certain new and useful Im'prove My invention is capable of a wide variety of uses, but'is particularlydesigned and adapted for attaching and detaching flanged hose or pipe such as are utilized by oil companies as part of their equipment at terminals, filling stations, and on tank steamers, barges and the like.

My invention has the advantage of avoiding the necessity of bolting and unbolting the usual flanged connections for supplying boats with fuel and loading and unloading liquid cargoes. Moreover, my invention is adapted to couple pipes of unlike size, and is adapted to cooperate with the standard flanges now in use on such parts.

Other objects and advantages of my invention will be set forth hereinafter, and

I will now describe the same with reference to the drawings and point out the novel features thereof in the appended claims.

Referring to the drawings, Figure 1 is a View in side elevation of a pipe coupling arranged and constructed in accordance with my invention and constituting one embodiment thereof.

Figure 2 is a view in end elevation of the same coupling with one of the pipes broken away and shown in section.

Figure 8 is a View of a longitudinal section of the coupling, taken on the line 33 of Figure 2.

Figure 4 is a partially sectional detail view, taken on the line 4 1 of Figure 3.

The pipe or hose connection shown in the drawings, comprises a body 10 of cast steel or other suitable material, having an ordinary pipe flange 11 at one end and a larger coupling flange 12 at the opposite heffi ng diie holes and is' adapted to be permanently ,1 coupled'to a corresponding flange on the oil header or connecti ship or" at a shore'stni a';

The :..ha .periphery ea;

threaded; pr iefab y by afla ne t e d;- as. shown at 1 5 to cooperate: withci .fila ni-P ll g ring or -nu't 16f whichfis correspondingly threaded o'n itsinterior]surfacei 'llh'e nut -16 has'dovetail-shaped notches" 1 8 011 its,

bed a tank" I exterior whichare,.adapted to be engaged by the, book 19 of i a' spanner V rench 20,

which is used for tightening "and loosening the Knot. Thej, flange 12 has. a ,pluralityfjof. slots 21 through whieh c1am ing jaws-22. extend and each of the -j awshasan inwardly extending lug "23 whichfis' 1 adapted to: en;

' gage the" ordinary flange 'such"as*24cof"the' pipe or hose which isto be coupled to the connection, and an outwardly extending finger 25.Which is adapted to be engaged by the clamping-nut 16.

At least one of the jaws 22 has a removable key 26 which extends through aslot or open ing 27 in the aw, and takes the place of the outwardly extending finger 25. The 'removable key is preferably connected to the body 10 by a chain 30 to avoid the possibility of its being lost. The jaw which has the removable key is obviously removable when the key is extracted andit may be attached to the body by a chain or other flexible con-. 7

nection, if desired. 7

The operationof the device is as follows: In making a coupling, assuming that the clamping nut is somewhat loosened, the re movable jaw is temporarily taken eut, thus permitting the flange 24 of the hose to be set into the other jaws. The removable jaw is then set in position and the key 26 inserted. It is thenonly necessary to turn the nut by the spanner wrench 20, so as to tighten the aws.

It is evident that any suitable-numberof jaws may be employed and that one or more of them may be removable to permit the flange of the hose or pipe being coupled to be set in position. I I

From the foregoing description, it will be readily understood that the connection. can be uncoupled asquickly and as easily'as it can be coupled. I

A structure of preferred form and construction has been illustrated and described for the purpose of showing a way in which this invention may be used, but the inventive thought upon V- which this application 1s based is broader than this illustrative'einbodiment thereof, and I therefore intend nolimitation other than those imposed by the appended claims. 7

7 What I claim is i 1 V 1. A connection or coupling cOIIlPIfisiIig a member having a notched'flange with its periphery screw-threaded, jaws mounted in the notchesof the flange and adapted to en gage the flange of a'cooperating member,

and a clamping nut screwed onto the periphery ofthe flange, and adapted to tighten the jaws.

2. A flanged pipe or hose connection, comprising a spoolhaving a circumferentially screw-threaded flange, with radial slots therein, clamping jaws mounted in the slots and each having an inwardly extending clamping lug adapted to engage the con necting flange, and an. outwardly extending finger on the opposite end, a; screw-' threaded clamping nut mounted on the periphery of the flangean dcooperating with? the fingers of the jaws.

3; A flanged pipe or hose connection, comprising a'spoolihaving a circumferentially screw-threaded flange, with radial slots therein, clamping jaws mounted in the slots and each having an inwardly extending clamping lug adapted to engage the connecting flange, andan outwardly extending finger on the opposite end, a screw-threaded clamping nut mounted onwtheperiphery of the flange andlcooperatingwith the fingers of the jaws, the finger on one: or more of the jaws being in the form of a removable key.-

.4. A connectlon or coupling comprlslng 7 a notched annular flange, a plurality of jaws in the notches and a clamping ring e'ngag.

ing all the aws, one or more of sa d aws V belng provided with removable means for engage the flange of a cooperating member,

and an adjustable annular member threadnamed flange for tightening the jaws.

In witness whereof I havehereunto set my hand this 15th day of May, 1922.
